SCANNING ELECTRON MICROSCOPY 523 (c) Figure 6. SEM montages of chapped skin: (a) before, (b) after i h, and (c) after 5 h applying "moisturizing" lotion. Note covering of uplifting layers after I h and onset of their reemergence after 5 h. Scale bars represent 300 tm• 2. Water was then patted onto the back of the hand, and after waiting oe0 min, the AFTER WATER replica was made (Figure 7(b) ). 3. Collasol* was patted onto the back of the hand exactly as was done for the water control followed by a gentle rinse. After 20 rain, the AFTER COL- LASOL PLUS WATER replica was made (Figure 7(c)). 4. "Collasol" was again applied, but not rinsed off, and after 20 rain, an AFTER COLLASOL replica was made (Figure 7(d)). The first point that is most readily apparent (Fig. 7) is the difference in overall appearance be- tween the two replicas with (Fig. 7 (c, d) ) and the two without (Fig. 7 (a, b) ) "Collasol." The BEFORE and WATER ONLY replicas show the manifesta- tions of dry skin by virtue of the presence of some uplifting layers, but both AFTER COLLASOL PLUS WATER RINSE, and AFTER COLLASOL show improvement over WATER ONLY. Such observations certainly provide *Croda, Inc., New York, N.Y.
